Irish authorities ordered all schools in the country to close Monday and warned cyclists and motorists to stay off roads as Hurricane Ophelia bore down on Ireland and the U.K. with potentially deadly winds.

Saturday should be mostly sunny with a high in the upper 50s and an overnight low in the lower 30s, according to National Weather Service meteorologist Jim Kalina. Winds of 20-30 mph are expected in the late morning with gusts of 40 mph in the afternoon.
